COMAC C919

The CJ-1000A wouldn't solve China's indigenization problems by itself. What about the landing gear, the avionics, and other systems, as well as how they all work together? The C919 is pretty much a foreign plane with a Chinese chassis. Kind of like how a "made in China" iPhone means the parts were imported into China and put together there.

And isn't the CJ-1000 itself reliant on Western parts? If I buy a Lego set from the store and snap the pieces together, that doesn't mean I can make legos in my house.

I would not be surprised if those other systems like avionics, APU, landing gear, could be leveraged from technology China developed for the Y-20. I know the MC-21 is going to use an APU derived from the one the Russians use in the An-124 for example.

As for the CJ-1000 I have seen no evidence that it is built with Western parts. There was talk that the Chinese were collaborating with the Germans initially in the program but from I understand that collaboration stopped a long time ago.

If you think that China can't build landing gears and avionics for a commercial plane when they've been doing it for years with military planes...

Second assembly line will be operation in Nanjing City in 2023. most of C919 units will produce from this line.

Shanghai Branch concentrate on C929 and next generation C939 ..

where will the future C929 and C939 be developed and made ?

Is the wing build in Xian ?

C929 will assemble in COMAC's main plant in Shanghai ..

about wing ? no information so far.

The cope and seethe from some western members are insane. LAMOOOO

ARJ-21 and C919 landing gears manufacture in mainland. and the main forging contractor is none other than Deyang Erzhong Wanhang .. China have luxury of 80'000 tons heavy forging machine.

As a supplier of Liebherr, Deyang Erzhong Wanhang forged landing gear forgings for C919. At the same time, it is also a supplier of Safran, forging landing gear forgings for B787, A320 and other models.. very few people know that, B787, A320 landing gears forging do in China. LOOOL

Wanhang can do this work, relying on the most important tool of the country - 80,000 tons of die forging hydraulic press. The video is the forging process of the B787 main landing gear outer cylinder forging. You must know that this forging weighs 4.3 tons. Because there is an 80,000-ton press, it only needs to be forged in two times. It only takes a few minutes from the furnace to the completion of the forging.




C919 cockpit also manufacture in China.






Compared with the general civil aircraft display system, the C919 not only has a larger display area, but also more abundant contents. Many aircraft in the same seat class use "small" displays of 8 inches to 10 inches, and many contents are displayed separately, and a single display only displays a certain type of information fixedly. However, the C919 adopts the "integrated display" technology. Various types of display information are highly integrated through software processing. Various types of data can be displayed on one monitor, and multiple monitors can be switched between each other. The man-machine effect is better. it is good. The comprehensive display technology of C919 is comparable to that of Boeing B787 and Airbus A350XWB, reaching the international advanced technology level.

There are reasons why C919 started off with Western suppliers for landing gears and avionics. It's not that Chinese companies cannot build these things, but rather they have certain requirements in terms of low maintenance/availability that Chinese companies have not proven they can meet. Most of the airlines themselves have years of experience working with Honeywell and other avionics companies. Getting a new unproven Chinese supplier on a brand new aircraft is hard for a lot of airlines to deal with. You are already trying to introduce a new fleet type, which is very costly for an airline. So, they want to put it in service with as much familiarity as possible. As they get comfortable with operating C919, it will be an easier sell to get operators to try Chinese suppliers.

If you think chassis is easy, Japan got a bridge to sell you.

You really are a broken record regarding Western suppliers.

We've heard you the 1st, 2nd, 3rd, 4th, 5th, 6th, 7th, 8th, 9th, 10th, 11th, 12th, 13th, 14th, 15th, 16th, 17th, 18th, and 19th time.

Just many times are you gonna keep repeating yourself, when the matter has already been discussed to death? Do you ever bring anything new and substantive to the discussions?

Please be considerate of the wider community. The Sinodefence Forum isn't a place for trolls or a substitute for therapy. If you need professional help, seek it, but please, for the love of God, either stick with your usual political threads or take your obsessive compulsive re-re-re-re-re-re-re-re-re-re-iterations somewhere else.

Please allow me re-iterate for the fourth time, only because you're incredibly hard of hearing: nobody gives a rat's arse about your umpteenth re-re-re-re-re-re-re-re-re-re-re-re-re-iteration. Come back to the flagship threads when you have something to contribute other than your persistent trolling masqueraded as obsessive compulsive re-re-re-re-re-re-re-re-re-re-re-re-iterations.

Please look carefully at the list of suppliers I sent before, OK?
